Specieatoa of Letters Patent.

Patented July 26, 1910.

Application led September 7, 1909. Serial No. 518,495.

To all 'whom 'it may concern: Be it known that we, VILLIAM H. WAL- DnoN and Louis R. KRUMM, citizens of the 1{.nited States of America, and residin d, refspectively at San Francisco, county o San Francisco, and State of California, and at Columbus, county of Franklin, and State of Ohio, have invented a new and useful Improvement in Antiseptio Mouthpiece-Cow ers, of which the following is a specification.

Our invention pertains to antiseptic covers for telephone transmitter monthpieces.

Cnr object is to provide a cover for in-Y suoli nature' as to be well adapted for advertising display.

In carrying out our invention we provide a sheet of thin material, preferably of paper,

.although it may be made of thin metal, celluloid or other similar materials. We provide an ear or a plurality of ears extending from the main surface of the thin sheet, which ear or ears are adapted to be clamped between the mouthpiece and the iront of the transmitter case by unscrewing the mouthpiece a portion of a turn, inserting the end of the ear or ears between the shoulder of the mouthpiece and the front of the casing, and clamping the ears firmly in place by again screwing the mouthpiece against its seat. As -an additional means for securing the flexible sheet or cover across the face of the mouthpiece, we provide slits in the paper or other material, which maybe snapped overthe front edge of the mouthpiece iii a manner that will be more fully hereinafter ex lained. A

y the means above broadly outlined, the sheet of paper or other thin flexible mate' rial 'is secured directly across the face of the mouthpiece so as to completely close the entrance thereof. It has been found that.

a sheet of thin flexible material thus placedbetween the speaker and the working diaphra *in of the transmitter, aiects in no niaterialzor appreciable degree the sound transmitting qualities of the transmitter, and at the same time it prevents the entrance of the moisture of the breath of the user with its attendant germs and foul odors.

.' Ihe front face of the cover may be provided with any suitable advertisin legend or insignia printed thereon, if the evice be made of paper or Celluloid, or embossed or etched thereon if it be made of metal. If of paper or brous material, we may impregnate the sheet with any well-known antiseptic fluid or deodorizer, so that the device may act not only as a means for preventing the entrance of gemis but may act in addition thereto as a germicide.

. In the drawings which accompany and form a part of this specification, Figure 1 shows a mouthpiece equipped with an attachment of the specific type shown in Fig. 3; Fig. 2' shows face view of the same; Fig. 3 shows an attachmentprovided with one ear and oneslit such as is shown also in Figs. l and 2; F ig. 4 shows an attachment having two ears and three slits; Fig. 5 shows face view of the same when in place upon a mouthpiece; F ig. 6 shows an attachment having three slits and without any ears.

F ig. 3 shows a sheet 1 of pper or other flexible sheet material of such shape as to conform to the requirements of its attach nient to the telephone mouthpiece iu the manner hereinafter pointed out. The method of attachment is shown iu Fig. 1. and .it will be seen that the end of the ear 3 clamped between the transmitter front 5 and the mouthpiece l by inserting the end of the ear in the space between the niouthpiece shoulder and the transmitter front, and therl screwing the mouthpiece home. The length of the ear 3 is such that it will reach approzimately to the front edge of the mouthpiece so as to allow the larger rectangular portion of the sheet l to bc bent down in front of the mouthpiece opening. The lower edge of the mouthpiece cover is fastened b v means of the slit 2. which is snapped over the lower front edge of the mouthpiece. forcing the flexible strip 2 which lies belowv thc slit Q, 'buck of the lower flaring edge of the mouthpiece, as shown clearly in Fig. 1.

The modified forni shown in Fig. 4 has two. ears 3 3 and may also be provided with two additional slots 2" 2". In this form the ears 3 3 extend on eachside of the shank ofthe mouthpiece, as indicated by the dotted circle in Fig. 4, and are clamped readily attached and readily replaced.

it is flat before attachment, and as it 1s not.

between the mouthpiece shoulder and the front in the same manner as previousl dcscribed. The front plate of the cov' r then bent down as hei'ore. and the sl t 2 made .o engage the lower tiarimgr edge ot' the mouthpiece. As additional security the vertical slots 2" 2 are provided for engagging' the Haring edge of the mouthpiec on each side. A

In Fig. t3 is shown an attachment which has :no ears, beingr self-supporting by its slots upon the mouthpiece. When engaged by the three slots it is held rigidly upon the mouthpiece and forms an eiiicicnt protectoxr,

provided with gum or other objectionable features, it may he carried in the pocket of the telephone user and attached to an;Y telephone transmitter he ma)- desire to use. The form of Fig'. preferably. is made of a reasonably-snif sheet of paper, such, for instance. as ll-pound, folio bond, although it ma)v he of any quality of paper desired7 the cheaper and lighter grades merely requit-ingr more delicacy in handlinfr.

rEhe slits. if desired, may be slots having an appreciable opening between their edges, a portion of the paper being punched out if Such form is preferred.

An important feature of our attachment the fact that it may carry advertising matter conveniently and conspicuously. This may be printed upon it either before ori` titer the paper is cutto forni our antiseptic attachment. since any form shown ma)y he fedconveniently to printingr presses. B v printing' advertisingr matter upon both sides the advertising matter always will be exhibited when thc device isi-attached to the transmitter. which is a cmumercial consideration ot' importance. f;

When it is desired that the mouthpiece Vcover .shall he antiseptic we saturate the paper. preferably after it is cut but before it is printed, in any of the well-lnown anti'- .scptic fluids. after which it is dried and printed or otherwise marked, as desired.--

The shane of thcperimeter of our attachment may he ofany desired form. Instead of malfiirgr it of substantially rectangular shape. the portion ot it which covers the face ot' the mouthpiece may be cut out in auf.' irregular or fanciful shape, such. forinstance. as the ell-known bell or shieldff which form the insignia of different telephone-using companies; The number and location ot the slots may als'o be made of any arrangement desired; for instance, two slots such as t3 G of Fig. 6, will hold the alttaclnnent securely, whether the .slots are verticali)Y disposed at the sides or are horizontally disposed at. the top and 'itnesses:

bottom.` ll'e do not wish to limit ourselves. ltherefore, to any spccilic arrangement o thc .slots or ears or detail ot' thc shape of perinwtcr of the device.

Having thus described our invention. what we claim as new and desire-to secure by V[,'nitcd `States laitier.- laient. is

1. ln an antiseptic mouthpiece attachment, a sheet oi thin material extending across the face of the transmitter mouthpiece and haring one of its edges adapted to he clamped between the mouthpiece and the transmitter front..

2. In an antiseptic mouthpiece attachmeut. a sheet of thin material extending across the face of the transmitter mouthpiece and having an ear integral therewith, adapted to be clamped between the mouthpiece and the transmitter front.

3. ln 'an antiseptic mouthpiecev attachment, a sheetof thin material adapted to he clamped at one. of its edges between the mouthpiece and the transmittet` face plate,

said sheet extending across the face of the transmitter mouthpiece and having a slit near its opposite edge for engaging'the front edge of the mouthpiece.

4. In an antiseptic mouthpiece attachment, a sheet of material; an ear integral with one of 'the edges of said sheet', said ear being adapted to he clamped between the mouthpiece and -the transmitter Vface plate, said plate having' near its edge, opposite said ear, a slit adaptedpto engage the edge of the mouthpiece when said ear is clamped, as described. A

5. In an antiseptic transmitter attachment, a sheet of resilient material having a plurality of eats and a plurality-ol-slits, said ears adapted to he clamped between the .mouthpiece and the face plate ota telephone transmitter`r and the slits radapta] to engage 'the edge of the mouthpiece.

6. An antiseptic mouthpiece attachment haringir two parallel slits spaeedapart a distance less than the diameter of the flaring edge of the mouthpiece, the edees of said slits being adapted to engage the opoosite sides of the mouthpiece and to hold said attachment in place upon the` mouthpiece.

7. In an antiseptic mouthpiece attachment, a sheet of material having at one side an ear adaptedto be clamped between the -mouthpiece and the transmitter face plate,

and having nearits edge opposite the ear, a slit adapted to engage the edge of the mouthpiece when the ear is clamped as described.'
